Description:

• The MBL8259A-2 is a programmable interrupt controller that is widely used in microprocessor systems to manage interrupt requests efficiently.
• This interrupt controller is perfect for lowering software and real-time overheads by effectively managing multi-level priority interrupts.
• Compatibility: Designed to function flawlessly with 8086, 8088, MCS-80, and MCS-85 microprocessors.
• Interrupt Capability: Supports up to 8 vectored priority interrupts, allowing the processor to prioritize and handle multiple interrupt sources.
• Cascaable: Can cascade up to 64 levels, allowing for sophisticated interrupt systems to be implemented without the need for extra circuitry.
• Programmable Interaction Modes: Supports a variety of programmable interrupt modes, giving flexibility for a wide range of applications.
• Individual Request Mask Capability: Allows for selective handling of interrupt requests.
• Operating with a single 5V supply simplifies power management by eliminating the requirement for a clock input.
• Package: The 28-pin Dual In-line Package (PDIP) allows for easy integration into a wide range of systems.
